Just a warning, do not conduct business with Rob at Midwest Performance Products in Diller Nebraska. He sells questionable quality parts, does not stand behind his work or the parts he sells.
The Pro Comp CNC castings are pretty nice, the valves, springs etc. he installed are JUNK! The springs are weak, the seat pressures are not close to consistent, the valves are VERY soft. He claims they came from Hughes Performance, if this is true, I don't have much faith in their parts either.
This is not a case of getting what you pay for, I specifically had him build them up for a roller set up, he knew exactly what I needed for my application.
I had under 20 passes on them since new.
My local machinest is fixing them, going to run all Isky components in them now. This is going to cost me a minimum of $1200 to do this but I will end up with a killer set of heads in the long run.
My recommendation is to get a bare set of the Pro Comp CNC castings and have your local shop build them with high quality parts. It may cost a little more to start with but the end product will be much better.
